And a sheath 4 which is extruded outside the communication unit 3 and the infusion tube 5 and protects the inside thereof.
In order to ensure the regularity of the inside of the optical cable and the convenience of manufacturing and processing, the section of the first resin layer 22 is arc-shaped, and the section formed by combining a plurality of first resin layers 22 is approximately circular in the circumferential direction of the optical cable; the second resin layer 32 has an arc-shaped cross section, and the entire cross section formed by combining a plurality of second resin layers 32 is also approximately circular in the circumferential direction of the optical cable, and the second resin layers 32 are provided so as to be bonded to the first resin layer 22.
Furthermore, in order to improve the stability of the rat and ant repelling effect of the optical cable, the capillary tube 6 is arranged on the inner wall of the infusion tube 5, the capillary tube 6 can adsorb a certain amount of rat and ant repelling solution, the capillary tube 6 can continuously and stably volatilize the rat and ant repelling solution, and the rat and ant repelling effect is stable. If the inner wall of the infusion tube 5 is not provided with the capillary tube 6, then when the optical cable is laid, the infusion tube 5 on the upper part will not contain rat and ant repelling solution, and the rat and ant repelling effect on the upper part of the optical cable is greatly weakened because the rat and ant repelling solution can only be carried out by the volatilized gas of the solution in the liquid storage part 1.
Still further, the inner wall of liquid storage part 1 also is equipped with capillary 7, and certain rat/ant repelling solution can be adsorbed to capillary 7 of liquid storage part 1 inner wall, compares in the liquid storage part 1 that the inner wall does not establish capillary 7, and the volume of the rat/ant repelling solution of storage increases to some extent, helps the extension of optical cable rat/ant repelling effect. In addition, along with the change of time, the rat/ant repelling solution liquid level in the liquid storage part 1 will descend, if the inner wall of the liquid storage part 1 is not provided with the capillary tube 7, the solution stored by the capillary tube 6 on the inner wall of the infusion tube 5 at the moment will be gradually reduced due to volatilization, and timely supplement cannot be obtained, so that the rat/ant repelling effect on the upper part of the optical cable is greatly weakened. After the capillary tube 7 is arranged, a large amount of solution is always adsorbed on the capillary tube 7 on the inner wall of the liquid storage part 1 due to the adsorption effect and the diffusion effect, and the solution reduced by the capillary tube 6 on the inner wall of the infusion tube 5 can be timely supplemented.
Furthermore, as shown in fig. 1 and 2, the outer end of each infusion tube 5 is inserted with a protrusion 8, the cross section of the protrusion is approximately triangular, the top end of the protrusion abuts against the inner wall of the sheath 4, the middle part of the protrusion 8 is provided with a cavity 81, two sides of the protrusion are provided with a plurality of through holes 82, the outer end of the infusion tube 5 is inserted into the cavity 81, in this embodiment, the through holes 82 are provided with two groups, the left and the right are respectively provided with one group, the through holes 82 are communicated with the infusion tube 5, and the rat/ant repelling solution is volatilized outwards through the through holes 82.

In addition, be equipped with non-woven fabrics 9 in the cavity that forms between sheath 4, communication part 3 and two adjacent transfer lines 5, non-woven fabrics 9 have certain hydroscopicity, and ventilative water permeability is good simultaneously, can save like unnecessary rat repelling ant solution that the transfer line of optical cable lower part flows out, can not influence the volatilization of rat repelling ant solution simultaneously, in the actual production process, also can set up other materials that have water absorption, air permeability in the cavity.
For a good fixation of the inner part of the optical cable, the non-woven fabric 9 and the outer part of the protrusion may be further wrapped with a wrapping tape 10 (also non-woven fabric) and then the sheath 4 is extruded.
In practical application, the optical cable needs to continue or cut, for accurate cutting and prevent rat/ant repelling solution loss, as shown in fig. 3, the liquid storage part 1 is provided with the partition part 12 dividing the liquid storage part 1 into a plurality of sections along the length direction of the optical cable, rat/ant repelling solution is stored between every two partition parts 12, and the corresponding sheath 4 is externally provided with an identification part convenient for cutting the optical cable.
